TWDDMM24DRF Discrete Module – 24V DC 16DI 8DO Relay

Product Overview

• TWDDMM24DRF is a discrete I/O module from the Twido series.
• It provides 16 DC inputs (24 V) and 8 relay outputs.
• Compact design with spring terminal blocks for easy wiring.
• Supports sink or source logic, flexible for most PLC systems.
• Ideal for small to medium automation control tasks.

Key Technical Data

• Brand: Schneider Electric
• Model: TWDDMM24DRF
• Inputs: 16 discrete, 24 V DC, 7 mA each
• Outputs: 8 relay outputs, 2 A per channel
• Input impedance: 3.4 kΩ
• Filter time: 8 ms (both state 0 and 1)
• Response time: ≤ 7 ms
• Isolation: 1500 Vrms (photocoupler)
• Common point: 1I / 2O configuration

Power & Environment

• Current consumption: 10 mA (5 V DC, all off) / 45 mA (24 V, all on) / 65 mA (5 V, all on)
• Operating temperature: 0…55 °C
• Storage temperature: -25…70 °C

• Certifications: CSA, UL, CE marked

Installation & Wiring

• Spring terminal blocks (TB_1, TB_2) for secure connections.
• Terminal labels clearly mark input numbers (IN_DIS#0~15) and commons (COM0_POS/NEG).
• Outputs use COM1#0-3 and COM2#4-7 commons.
• Supports both sink and source wiring without extra components.

Compatibility & Use Cases

• Works with Twido PLC base units and standalone.
• Suitable for conveyor control, packaging machines, and small assembly lines.
• Ideal for HVAC, lighting control, and simple sequencing tasks.

Expert Review

• “Reliable workhorse for discrete control. The relay outputs handle inductive loads well.”
• “Fast response and clear terminal labeling reduce installation errors.”

Manager’s Insight

• “Cost-effective choice for OEMs. Stock availability and 12-month warranty add value.”
• “Easy to integrate into existing Twido systems – no rewiring headaches.”

FAQ – Frequently Asked Questions

• Can I use this module with 12 V sensors?
  No, the input voltage range is 20.4…28.8 V DC only.
• What is the maximum current per common?
  7 A per output common (COM1 or COM2).
• Does it support PNP or NPN sensors?
  Both sink and source logic, so it works with PNP (source) and NPN (sink).
• How do I connect the common terminals?
  Use COM0_POS for inputs and COM0_NEG if needed – see terminal diagram.
• Is the module hot-swappable?
  No, always power off the system before inserting or removing the module.
• What is the typical lifespan of the relay outputs?
  Over 100,000 cycles at rated load (resistive).

Selection Guide

• Choose this module if you need 16 inputs and 8 relay outputs in one compact unit.
• For all-transistor outputs, consider Twido‑DMM…DRF variants (not this model).
• Check your total output current: each channel 2 A, common max 7 A.
• Verify input impedance matches your sensor output (3.4 kΩ typical).
• If your ambient temperature exceeds 55°C, use a forced-air cooling cabinet.

Delivery & Support

• Shipping: Ships within 12‑24 hours after order confirmation.
• Carriers: FedEx, UPS, DHL – worldwide express.
• Warranty: 12 months against manufacturing defects.
• Package includes: Module, terminal blocks, and user manual (digital).
